A new method allows detecting the transmission of SARS-CoV-2 in indoor air in hospitals
13 October 2021
The Institute for Environmental Assessment and Water Research (IDAEA-CSIC), and the Hospital Son Espases (Mallorca) have developed a new methodology to measure the presence of the SARS-CoV-2 coronavirus in the air of hospitals. The study, led by the researcher Joan Grimalt and his team, has shown that the air in the corridors may have higher levels of viruses than rooms with Covid-19 patients. This result is explained by the fact that rooms have individual ventilation systems, while corridors have only one system every four rooms. The results of the study could be used to review the ventilation systems of the hospitals, improving their indoor air quality and preventing the infection of health personnel.
